Study on Nutrient Management Technology for Vegetables in Wuhan

Over fertilization for vegetable in Wuhan is very serious problem. Therefore, supported by IPNI China program, the project cooperators in Wuhan Academy of Agricultural Science carried out this research project to study the better nutrient management strategy for the main vegetable crops in Wuhan region in recent years.

IPNI-2010-CHN-HB40

Vegetable planting area in Wuhan reached 167,000 hectares with many different species and varieties, amount them eggplant and bolt rape are two of the main species with 4,000 ha eggplant and 6,500 ha bolt rape. The bolt rape occupied 50% of whole China. Farmers usually use compound fertilizer (15-15-15) and urea as commercial fertilizers for the vegetables and always unbalanced application fertilizers.

Interpretive Summary

Red flower stalk is one of the main vegetables grown along the Yangtze River valley in Hubei, Hunan and Sichuan. Hubei is the largest red flower stalk production province in China, with a total planting area of 53,000 ha. At present, unbalanced fertilization frequently limits red flower stalk yield and quality.

Red flower stalk is one of the main vegetables in Wuhan region. However unbalanced fertilization frequently limits its yield and quality. This project was started in 2011 to study the benefit of proper nutrient management practices for improving red flower stalk yields and quality. Treatments include five application rates each of N (0, 300, 600, 900, and 1,200 kg N/ha), P (0, 150, 300, 450, and 600 kg P2O5/ha) and K (0, 225, 450, 675, and 900 kg K2O/ha).

In 2012, an on-farm fertilization trial on eggplant was completed. Results showed that with the increase in N fertilization rates, eggplant yield and tissue nitrate content increased gradually. With the increase in P fertilization rates, eggplant yield increased at first up to 180 kg P2O5/ha application and then decreased.
